摘　　要：某风电场2020年发生多次风机跳闸脱网及SVG因谐波超标不能正常投入运行故障。为了确保风电场电气设备的安全稳定运行,对现场开展电能质量测试,分析事件原因及研究治理措施,为风电场电站电能质量治理提供科学的数据支撑。In 2020,a wind farm experienced multiple wind turbine trips and out-of-grid failures and SVG failures due to excessive harmonics that could not be put into operation normally.In order to ensure the safe and stable operation of the electrical equipment of the wind farm,the power quality test is carried out on the site,the cause of the event is analyzed and the treatment measures are studied,so as to provide scientific data support for the power quality treatment of the wind farm power station.
